Xeno

Xeno is an sentient artificial intelligence created by an unnamed scientist, originally derived from encrypted code from the Xenothium core discovered by the same scientist, and later retooled by Dr. Cyanide. Xeno is the archenemy of Zero. Xeno quickly became corrupted due to the malicious nature of the Xenothium core. Killing his creator, Xeno went on a rampage and became a rival to Zero.

Launching the Xeno Offensive, Xeno made robotic versions of the heroes still present at that time and succeeded in taking over the world but was eventually defeated by Zero. Returning 5 years later, he restarted his campaign and disappeared in a flash of light. Going back in time, he once again launched his Xeno Offensive and created an army of robots to combat Team Zero, the Legends, and Team Silver, aided by Dr. Cyanide. However, Xeno was ultimately destroyed by Zero and the robots salvaged by the Arsenals.

But shortly before his destruction, he had planted his consciousness in another body and returned to fight Zero but was destroyed once and for all after a brutal fight. The Xeno Offensive made a young scientist realize the threat that superhumans posed to humanity and conceived a plan to create a peacemaking program in the form of a robot to eliminate future threats, thus leading to the creation of Xeno in a loop.
